Synthesis of a novel porphyrin bearing chloroper-fluoropolyether moieties with very high solubility in supercritical CO2

A new porphyrin bearing chloroper-fluoropolyether substituents at the meso positions was prepared in five steps starting from chloroper-fluoropolyether carboxylic acid. Metallation of this porphyrin was accomplished with cobalt and zinc. Both the free base and its complex with zinc are highly soluble in supercritical CO2 under very mild conditions (40°C and 20 MPa) thus allowing, in principle, homogeneous catalytic processes to be performed in this non-conventional reaction medium.
